This project was started in , electronics and control loops. Because I always need a cool project to learn new things, it was clear that something that can fly had to be built.
The project started as a "tricopter-only" project, but as I wanted to build smaller vehicles with more payload capacity, I decided to make some quadrotor, hexacopter and Y6 hexacopter firmwares too. My main interest is to build very small MAVs that fly as good as larger ones (or even better) and that can be controlled by wireless video link. I also experimented with autonomous flight in GPS-denied areas (video), and with GPS assisted autonomous hover (video).

First flight - derbe evo

The copter had its first flight yesterday. With the 5.5" Graupner Race-Props, the speed is absolutely amazing - I still need to learn how to control such a fast device properly.

Here is a quick + dirty video:

And Shrediquette is still open source of course, so here are the 3D files:

The arms are from the Claerials HUMs quadrotor: http://claerials.com/shop/hums-ersatzarm/

  1. Is the battery in the picture 1.8Ah 4S? If so do you have a link for it? It is nice and stubby. I have a similar setup but with a vac formed shell rather than a 3D print and the limiting factor to the front profile is the battery size. Smaller batteries don't hold up for very long at full throttle.

    1. No, this is only 1.3Ah, 75C. When I really want to go fast, I need to install the 1.8Ah 75C. The current draw is just too high for the 1.3Ah Lipo...
